The Commens Dictionary

Quote from ‘On the Logic of Quantity’


a science ought not to be defined, as it often is, as a systematized collection of ascertained truths; because it is more useful to those who know it best that it should refer to the scientific activities of its promoters. Its essence ought therefore be made to lie in the investigations and their enlightened methods and not in the results and their truth. Moreover, every inquiry which can be properly performed only by those who are engaged upon the main branch of inquiry should be included under the science.
